Letters Patent No. 106,184, dated August 9,1870.

IMPROVEMENT IN GRAIN-SGOURING- MACHINES.

The Schedule referred to in these Letters Patent and making part of the same i a I I 5 To all whom it may concern: I a

Be it known thatI, WILmAM'MoLAUGHms, of'

JerseyGity, in the county of Hudson and State. of New. Jersey, have invented a new and improved, Grain scouring Machine;.and I .do hereby declare that the following is a' full, clear, and exact description thereof, whiolrwill enable others skilled in the art to make and use thesame, reference being bad to the accompanying drawing forming part of this speci-- vfication.

g This invention relates to improvements in machines for scouring and hnlling grain, and consists in arranginga scroll-shaped groove in the face of one of the stones, preferably the runner, beginning at the center and gradually approaching the skirt, and in arranging the said grooved stone with another stone having a smooth face, which will confine the grain in the scroll groove, and cause'it to be subjected to the action of the stone during several revolutions, the said groove preventing the escape of thegrain as soon as it does in the stonesas ordinarily arranged, and causing a more uniform action.

Figure lis sectional elevation of .my improved mill, and Figure 2 is partly a plan and partly a horizontal section. Similar letters of reference indicatecorresponding parts. I propose to make a broad scroll groove, A, in .one of the stones, preferably the runner, with vertical sides, and about or nearly as deep asthe thickness of said points, which would not act on the grain if the wall terminated at B, as the grain escapes at the end' the grain to lac-acted on, the said groove beginning at the center of the stone, extending several times around, and terminating at the periphery, where it'is made concentric nearly one circle, say from the point ll, where the dividing wallcomes to" the periphery, to the point 0, leaving a narrow place for the discharge, thereby utilizing the surface of the stone between the of the said wall.

It will bc'seen that the action of a stone on the grain arranged in this way,'.-and combined with a stone, 0', having a smooth face,'will be continued muchlonger, and will be much more uniform than when the common dress is used, which allows the grain to escape more directly.

. By this plan, the pressure of the stone upon the grain does not require to be so great .as to elfect the necessary-work, and thereby the tendency to break the grain is very much lessened.

I also propose to place the scraper on theunde'r side'ot' the running stone, toprevent the grainfrom working under it.

I also propose to apply a sucker-spout, E, and fan forremoving the dirt from withinthe curb, and, to

supply the air for the purpose, I makeholes in the side of the curb, as shown at F.

Instead'of forming the spiral channel by making the groove in the face'of the ,stone'or scouring-plate,

1 may make it by attaching a spiral rib to the face of being setfurther toward the skirt than the first, su'

that the groove or space will assume the equivalent of a spiral course by the successive breaks in the rib.

- Or, again, these sectional ribs may be plain or in any other form, which, when arranged accordingto the plan indicated, will obstruct and regulate the passage of the grain to the skirt, in the manner described.

Having thus described myinvention,

I claim as ncwand desire to secure by Letters Patent The combin ation of one smooth-faced stone with'a .stone having one continuous groove, forming a coil upon its surface,-as shown in fig. 2 of drawing.

The above spccificationof my invention signed by me this 17th day of May, 1870. g 7 WILLIAM MGLAUGHLIN.
